ContinuationFilter must be applied to servlet paths that make use of
the asynchronous features provided by Continuation APIs, but that
are deployed in servlet containers that are neither Jetty (>= 7) nor a
compliant Servlet 3.0 container.

The following init parameters may be used to configure the filter (these are mostly for testing):

debug

Boolean controlling debug output

jetty6

Boolean to force use of Jetty 6 continuations

faux

Boolean to force use of faux continuations

If the servlet container is not Jetty (either 6 or 7) nor a Servlet 3
container, then "faux" continuations will be used.
